Definitions
- the invention relates to a housing, in particular for accommodating the electrical and mechanical components of an audio, video, or navigation system in a motor vehicle.
- a housing is provided with side walls which are of an integral and collapsible construction, which in the collapsed state form the housing, and which are provided with functional elements and closing elements of synthetic resin injection-molded onto the housing walls, while the closing elements are arranged so as to be movable.
- the housing walls comprise the bottom, the top, and the rear and front walls. These walls are movably interconnected by means of bending seams and may thus be laid out flat.
- the bottom is manufactured as a self-supporting carrier plate and thus gives the housing the necessary stability.
- the housing walls can be manufactured in one operation in that they are stamped out from sheet metal. Then functional elements and closing elements, which additionally stabilize and also close the housing, are subsequently injection-molded onto the housing walls by the outsert technique. This renders possible a cost-effective and fast manufacture in large batches.
- the embodiment as defined in claim 2 presents a particularly simple possibility for fastening electronic components and other components in the housing.
- the side walls are also fastened in this manner. Snap connections are provided for this purpose on the housing walls, into which the components are simply inserted so as to be snapped home and retained.
- Such a stable fastening is also ideal for heavy components such as CD/DND drives.
- Welded joints and screw connections are unnecessary in this way.
- the embodiment of claim 3 renders it possible to lock the housing after collapsing in a simple manner without additional screws or welded joints, which locking can be undone in that the closing elements are turned into their original position again.
- the major advantage of claim 4 is that the electronic and electrical components provided in the housing are interconnected without the use of cables. An expensive wiring system is made unnecessary thereby.
- Claim 7 defines a method of manufacturing a housing according to the invention.
- the housing walls are integrally stamped from one piece of sheet metal here. This renders possible a single-step and cost-effective manufacture of large batches.
- the synthetic resin components are injection-molded thereto. This is also possible in one operational step with the outsert technique.
- the embodiment according to claim 8 allows of a particularly simple mounting of components to the housing, because the latter is freely accessible in the folded- out state.
- the embodiment according to claim 9 renders any cabling unnecessary.
- the devices necessary for the attachment of cables may thus be left out.
- the absence of cables means a saving of space in the interior of the housing.
- the embodiment of claim 10 renders it possible to fold the housing module into shape in a simple manner after the provision of electronic components, drives, etc., and to secure it in a reliable manner by means of the movable closing elements, so that no screw connections are necessary, which simplifies the manufacturing process.
- the electrical connections between the individual components are achieved simultaneously with the folding into shape of the housing module. This may thus be achieved in one process step in the manufacture of the housing. The laying of cables between the individual components thus becomes redundant. This represents a further considerable simplification of the manufacturing process.
- Fig. 1 shows housing walls with a carrier plate in the folded-out state
- Fig. 2 shows the housing walls with the carrier plate provided with functional and closing elements
- Fig. 3 shows the housing walls in the process of being additionally provided with side walls, a drive unit, and a control circuit board,
- Fig. 4 shows a housing fitted with components during folding into shape
- Fig. 5 shows a housing with closing elements in the closed state and with a control panel which is to be attached thereto.
- the housing walls 1 are preferably made in one piece and comprise a carrier plate 7, onto which in a later stage the electromechanical and electronic components of a car radio or a navigation system will be mounted, as well as the top and the front and rear walls.
- a particularly suitable material is metal, i.e. the housing walls 1 can be stamped out from a sheet of metal.
- the stamped-out housing walls 1 are visible in Fig. 1 in the original developed state, i.e. the way they issue from the stamping machine.
- the sheet metal is flexible in the transition zones between the carrier plate 7 and the side walls and between the rear and the top, so that the housing walls 1 can be collapsed later.
- the bending possibility is achieved by means of grooving and other treatments. It is also possible to provide the bending seams with recesses and to provide synthetic resin hinges therein. These hinges would then be manufactured in the next step as described below.
- a second step functional elements 8 and closing elements 5 are injection- molded onto the housing walls 1. This is done by the so-termed outsert technique. All synthetic resin elements are thus provided on the housing walls in one step and are indetachably joined thereto. An additional feature is that the synthetic resin elements may be made of different materials which are injection-molded simultaneously or in quick succession. The result of this manufacturing step is shown in Fig. 2.
- Fig. 4 shows how the housing walls 1 are folded (collapsed) into shape.
- the plug-and-pin contacts 9 of the electrical components are at the same time connected to one another, so that all electrical connections are established the moment the housing is closed. Any cabling becomes redundant as a result of this.
- the housing is locked in that the closing elements 5 are rotated as shown in Fig. 5. It is alternatively possible to use sliding closing elements instead of rotating ones.
- the front panel 6 with operational controls is attached to the finished housing, as is also shown in Fig. 5. The electrical connection is again achieved by means of plug-and-pin contacts here.
- the functional elements 8 and the closing elements 5 as well as the recesses in the housing walls 1 necessary for the snap connections are shaped such that many arrangements of drive units 4 and printed circuit boards 3 are possible. For this reason, more recesses are present than are necessary for a given single product.
- One and the same housing may thus accommodate cassette radios, radios with CD/DND drive units, or navigation systems, as applicable.
- the housing according to the invention may obviously also be used for other appliances, in particular for components of HiFi systems or for video recorders and DND players.
